PROCESS OF MAKING THREAD.

No Drawing.

a method which is extremely inexpensive, reliable requiring noparticular skill, and productive of sur-.

prising and novel results.

Where I have attempted to produce ornamentations upon a fabric base bythe deposit of a plastic mass thereon, I have found that the plasticmasses hitherto employed by me have been of such a character that inorder to give the desired ornamental effect, the

0 de osited material had to be treated either be ore or after the deosition thereof, as by flocking, so as to pro uce the desired result.More specifically, where the effect desired was an ornamentation whichwould resemble the effect produced by the utilization of genuine silkthread, the material deposited, in general had to be treated with acoloring matter which would impart to the surface of such depositedmaterial an appearance of silk. 7

' Accordingly, another object of the present invention is to provide amethod of producin a fabric of this nature, wherein the necessity forsuch treatment has been eliminated, and wherein the material depositedwill in and of itself and by virtue of its own inherent characteristicsproduce the desired efi'ect. I 40. More specifically, it is an object ofthe invention to produce a fabric of this character which will resemblethe type of fabric which is produced by the utilization of silk threadwhich has been obtained fI'OIIlllIlCllltivated silk worms.

Another dbject is to produce a fabric which will bear ornamentations ofthe na 'ture and appearance of silk embroidery, without howeverencountering any of the difliculties or expense generally involved ingenuine embroidery work. A feature of the invention lies in the directdeposition of a material like viscose in accordance with a predeterminedplan, upon a fabric or its constituent threads.

For the attainment of the foregoing ch- A further object lies inproducing such Application filed August 2 7, 1925. Seriallio. 52,958.-

jects and such other objects as may hereinafter appear or be pointedout, I shall now describe several processes which are illustrative ofpossible modes of. carrying out my invention.

It .is a well-known fact that silk thread which is obtained fro mimperfect or freak cocoons, 'or from the-.;cocoons of wild oruncultivated silk 'worms,"will be irregular in texture and will carrynub s,.or thickened portions, at frequent irregular intervals. Thesevery imperfections, however, have been utilized to effect anirregular,yet pleasing, ornamentation upon fabric, by manu- 3 facturingthe fabric of these imperfect threads.

One of the objects of my invention is the production of a thread whichsimulates this imperfection, and more particularly the proferred to.Where the imitated nubs are as ,sociated with an already formed thread,the

viscose is preferab y preparedv .in' the form' of a pasty mass, and madev available as require re-determined quantities or obs of the mass maybe depositedupon the ase thread at suitable irregular intervals, and theinherent characteristics of the viscose will cause it to harden and tobecome part and parcel of the thread in such a manner that the resultingthread will be hardly dlS- tinguishable from the genuine productobtained from the uncultivated cocoons. The f.

fabric is then woven-in alwell-known man- 'ner, and ornamentations willresult which will be artistically irregular in accordance with theredetermined plan/ It will this process will permit of the deposit ofviscose masses at regular intervals, if dee obvious that a modificationof sired, in accordance with any predetermined or desired artisticscheme, and the resultin fabric will have an unusual ornamental e set,in that it will appear to ave been .made from imperfect genuine silthreads,

yet hearing at the same time designs having certain features ofregularity.

In order to carry out and fully attain the objects of my invention, Imay control or vary the quantity of thread material thereby forming theirregularities, nubs, or thickened portions and I preferably, althoughnot necessarily, do this in a predetermined manner so as moreeffectively to produce the new and desired results. This controlled orpredeterminedly controlled varying of the quantity of material may beaccomplished in many ways. As Jan example, I may obtain a surging actionby providing for the irregular operation of the pump acting to force thevicose material through the dies, whereby the viscose material is moreor less rapidly forced through said dies at the irregular impulsestrokes of the pump. This has been found to effectively produce theintended results as the irregular impulses may readily be given to thepump through the use of cam arrangements. Such an arrangement would,moreover, lend itself to any desired predetermined control as the camfaces can be contoured to give any predetermined or controlledirregularities. As a further example of an eflicient manner of carryingmy invention into effect, I may associate with the main pump forcingtheviscose material through the dies, an auxiliary pump which may vary thepressure at the extruding orifices of the dies, or the amount ofmaterial passing therethrough in a given time, or both, and thus againfully effectuate my present invention.

Another method of carrying out my invention is the result of carryingthe basic idea a step further. Instead of depositing the viscose atregular intervals upon a base thread and thereupon weaving the fabric,it is possible and often preferable to de osit the viscose in accordancewith a pre etermined plan of ornamentation upon a finished base fabric,that is, upon a fabric already woven. In accordance with this method, abase fabric, such as cotton, may be rendered ornamental by directlydepositing viscose thereon in predetermined quantities and masses andalong predetermined lines or areas, and by virtue of the fact that thedeposits will become part and parcel of the ase fabric, the result willbe one of a fabric bearing silk ornamentations. In accordance with thismethod, the material which has been selected as a base, either silk ornon-silk, as desired, is suitably laid out and may if desired bestenciled or similarly imprinted in a temporary manner with theparticular design in contemplation, although this preliminary outliningof the design is not an essential step. Viscose is then prepared in thesame manner as hereinbefore described, namely, in the form of a pastymass, and is made suitably available in any preferred manner. One methodof rendering the viscose available for this purpose is to insert it intoa plurality of tubes having outlet openings of varied sizes andconfigurations, whereby viscose streams of desired thicknesses or massmay be expelled by pressure uponthe tubes. The tubes are thenmanipulated in any desired or preferred manner as in the manner ofpencils, and the viscose is deposited directly upon the base fabricalong lines or areas dependent in size, length, and configuration uponthe particular ornamentation which has been decided upon. Thereupon thedeposited material is allowed to dry, whereby it will become closelyassociated with the fabric in a manner to become part and parcelthereof. A deposition process similar to printing may also be employed.

In cases where the deposits have been made along lines simulating.embroidery, the resulting ornamentation will not only resemble genuineembroidery, but will consist of actual artificial silk integrallyassociated with the fabric as though genuinely produced by embroideryprocesses. Accordingly, theadvantages of silk embroidery work areobtained without any of its disadvantages having been encountered.

Although not essential, it will be obvious that the viscose may besuitably colored before application, or,that suitablecoloring matter inthe form of a deposited powder or the like may be added to it after ithas been applied to the fabric.

It will be obvious that various changes in the details as hereindescribed for the purpose of explaining the nature of my invention maybe made by those skilled in the art without departing from the spiritand scope of the invention as expressed in the appended claims, and itis therefore intended that these details be interpreted as illustrativeand not in a limiting sense.

It will be observed that in the specification and claims the term threadmaterial is-intended to apply to the material forming the thread,whether plastic or otherwise. or to the subsequently formed thread.

The irregularities herein referred to have been described as simulatingthose formed by the uncultivated silk worm cocoon. It will beunderstood, however, that such need not be the case.

In the claims where I make reference to forming a fibre or thread withirregularities thereon by associating with the thread materials suchirregularities by. a predetermined controlled or varying quantity ofmaterial, I mean to include thereby such additions or variations as willgive an irregular or ornamental effect in accordance with somepredetermined scheme or plan to obtain effects of definite irregularity,and not merely accidental, such as might be caused by an improperhandling of the mechanism or coagulating baths affecting merely in anundesired manner the filamentor thread for purposes of weaving, knittingor otherwise handling the filament or thread for forming a fabric.

Having thusdescribed my invention and illustrated its use, What I claimas new and desire to secure by Letters Patent, is:

1. The herein described process of making thread for ornamental fabric,which consists in depositing viscose in substantial relief upon a basematerial in the form of a thread in accordance with a predetermined planof treatment or relief ornamentation.
